Do you have the govee app you can calibrate them with it. If you have a dehumidifier that shows the rooms current humidity I would calibrate it to that
I use the Govee minis. But I also calibrate them. I throw them in a jar with a 62% Boveda, leave them overnight, and then adjust them all to read 62%. That way they are reasonably accurate, and consistent…
I have a 2x4 tent with two plants. One is about 6 inches taller than the other. I position the probe between the two and about canopy height of the shorter plant?
Tough call with the different heights. I just try to keep it close to the canopy, but high enough to be in active air movement, so it’s not reading a pocket in, or transpiration of, the plants themselves.
The tent with both the inkbird and ACI is set up to dry right now, so the ACI turns on at 60% and the Inkbird turns the humidifier on at 55% (I think, I’d have to double check exact numbers)… point being, they don’t fight each other and they track together much better than I expected. At this point in my exposure to hygrometers, I chalk it up to both being top grade probes on controller assemblies. Of course that’s just an opinion…
Any chance you can raise the shorter one by putting something under it? If so, then place you probe at mid-level of the plants, and know that it will be slightly dryer above, and slightly more humid below.
